LED outdoor digital signs are the most effective means of advertising/promotion available to a retail/storefront establishment and it's important to understand that the LEDs are actually a consumable. In other words, the LED lamps tend to dim out over time and since an LED digital sign is good for 80,000 - 100,000 hours, there are some tricks that we use to extend the useful life of the sign. First, set the scheduler in your LED control software for the sign to shut off from 12:00 midnight until 6:00 am. This will help increase the effective life of the sign from 7 years to 10 years. Secondly, use the auto dimmer capability of your sign. Today's LED sign is meant to be clearly seen during the middle of the day so they are extremely bright. By using the auto dimmer to reduce the brightness as night falls you will extend the life of your sign by several years.
